Question 1

What is UV disinfection and how does it work?

Accepted Answer

UV disinfection uses ultraviolet light to inactivate microorganisms by damaging their DNA, preventing them from reproducing. UV-C light (254nm wavelength) is most effective for water treatment, providing chemical-free disinfection without affecting water taste or odour.

Question 2

How do I choose the right UV system for my application?

Accepted Answer

The right UV system depends on several factors including flow rate, water quality (UV transmittance), target organisms, and specific application requirements. Our UV specialists can help you select the appropriate system based on your needs. Contact us for a consultation.

Question 3

How often do UV lamps need to be replaced?

Accepted Answer

UV lamps typically need replacement every 9,000-12,000 hours of operation (approximately 12-18 months of continuous use). However, the lamp replacement schedule may vary based on water quality, usage patterns, and specific system requirements. Regular monitoring ensures optimal performance.

Question 4

What maintenance is required for UV systems?

Accepted Answer

Regular maintenance includes: replacing UV lamps as per schedule, cleaning quartz sleeves to remove mineral deposits, checking UV intensity sensors, and replacing O-rings during lamp changes. Most systems require minimal maintenance compared to chemical treatment methods.

Question 5

Are Advance UV systems certified?

Accepted Answer

Yes, Advance UV systems are WaterMark certified, meeting Australian standards for water treatment equipment. Our manufacturing facility is ISO9001:2008 certified, and UV dose calculations are verified with independent third-party software.

Question 6

Can UV systems remove chlorine or other chemicals?

Accepted Answer

UV disinfection does not remove chemicals from water. However, specific UV wavelengths can destroy chloramines and reduce TOC (Total Organic Carbon) in specialized applications. For comprehensive water treatment, UV is often combined with filtration or other treatment methods.

Question 7

What is UV transmittance (UVT) and why does it matter?

Accepted Answer

UV transmittance (UVT) is the percentage of UV light that passes through water at 254nm wavelength. Higher UVT means clearer water that allows more UV light penetration. Most UV systems require minimum UVT of 75-85% for effective disinfection. Pre-filtration may be needed for low UVT water.

Question 8

Do you supply spare parts for other UV brands?

Accepted Answer

Yes, Advance UV stocks replacement lamps, quartz sleeves, sensors, and other parts for most major UV brands used in Australia, New Zealand, and Oceania, including UV-Guard, Wedeco, Xylem, Sterilight, Trojan, and many others.
